CAR-D001?, LOCK.

Application filed February 23, 1918. Serial No. 218,638.

T 0 all whom t may concern.'

Be it known that I, EDWARD A. MAYHEW,

a citizen of the United States, 'residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Car-Door Locks, of which the following is a full, clear,.and exact descri tion.

y invention relates to car' door fastenings and` particularly to the type of fastenings in which a hasp is locked to another member by means of a lock pin or other suitable locking means and'also in which a seal wire or metal "ribbon is employed for indicating an unauthorized opening of the car door. In some respects the invention relates to improvements on the type of door fastener described in Letters Patent of the United States grant- `ed to R. S. Miller April 111th, 1914-4, No.

One object of my invention is the construction of. a door fastening in which the hasp.

or `other portion of the fastening, if broken,

\ may be replaced without necessitating the replacement of the entire fastening.

Another object is the provision of an improved hasp and locking member therefor i which are not so easily broken as the exist- `ing forms of hasns and lock members by the rough usage which railway car door fastenings .usually receive. 4

The invention consists inthe novel and improved constructions,` arrangements and combinations to be hereinafter described and claimed for carrying out the above stated objects and such other incidental objects as may appear from the following description of a preferred embodiment-of my invention.

In the drawings:

Figure 1 is a front view of my improvements.

Figure 2 isl a top edge view of the same showing fragments of the door-frame and the car door to which it is attached.

Figure 3 is a horizontal section taken on dotted line 3 3, Figure 1.

Figure 4 is a horizontal section of said improvements taken on dotted line 4 4, Figure l.

Figure 5 is a vertical section taken on dotted line 5-5, Figure 1.

Figure 6 is a vertical section taken on dotted line 6-6, Figure 1.

Referring to the drawings, 1 represents the sliding car door; 2 the door post, and 3 4the door-stop 3 the strain of the door-stop; 5 is a horizontal plate which is secured to the outer surface of the door with Vone end next the forward edge of the same, 'and is so constructed that its opposite end portion stands out away from the surface of the door and terminates in a loop or staple 6. The extremity 7 of this staple is provided with a cross-head or T-head 8 the lobes of which extend laterally, substantially as shown in the drawing-gs, and this headed extremity is adapted to enter and be retained in a pocket 10 in a boss 11 in a plate 12, which latter is secured to the door in alinement with plate and has a tenon 13 on the contiguous end thereof that is inserted under the outstanding portion of plate 5 and enters a recess in the shoulder at the root of said outstanding part of plate 5 and prevents the lateral displacement of the one with relation to the other. The entrance to pocket 10 is elongated longitudinally and corresponds in dimensions to the rectangular dimensions of head 8and when assembling plates 5 and 12, plate 12 is first placed at right angles to plate 5 and then after the cross-head is inserted through Ithe longitudinally elongated entrance of the pocket said plates are moved into alinement and secured in this relative position to the door.

A hasp 14- is secured to staple 6 in the usual manner, the eye 15 thereof being elongated longitudinally sufficiently to enable the crosshead of the staple to be passed therethrough. VVhen'the hasp is locked to the Dart of the door fastener that is secured to the hasp will pullagainst the root of the staple, at which point the staple is stronger and less liable to break than the free end thereof, which, when constructed as disclosed in the aforesaid patent it is more liable to do.

rIlhe end of the hasp opposite the staple is provided with a head 16 that consists of an integral rectangular member which corresponds in width to the same and projects at right angles to the fiat sides thereof. The outer face of this head has ribs 16a projecting outwards therefrom that strengthen it.

The locking member with which the hasp is adapted to engage to lock the door is secured to the outer surface of the door stop and comprises a. vertically disposed plate 17 which is secured to the outer surface of doorstop 3 by bolts or rivets 18, 18. that pass through its ends and has a thickened e portion or block 19 between its ends Whose outer flat surta-.ce is provided at one end with a loop 20 and at the other end with a socket member 22. rEhe socket member corresponds in construction te the socket inember. disclosed in the said Letters latent 1,029,989 granted to S. l'vfiiller, and the hasp, when the door fastener is loelrad, is between loop 2O and said socket, Vflat against the outer eurtace ot bloclr 19, and so that the, branch oi' the head thereof pro jeetingY toward the car Will bear against 'the sido oit said block farthest from the car door.

llasp 'lei is held on seat by abolt 2l that corresponds in construction and operation to bei i0 ot the aforesaid patent, and one end thereot enters and is secured in the scelte-t 22 one side ot the hase, and extends thr i loop 2O at the opposite side et said hasp, .,d thus it is unneccesar)Y ttor an ele-nf gated slot or eye to be made in the hasp 'tor the loop to paas throneh as made in the hasp oit the said l'lillei ent. The bolt et said pat-ent Simply perlormed the function o1? retainii'rpla the hasp on its ln nij'r inrcntion the portion ot head lo eng( L.; the side of block 19 should break, the part ot the head projecting' outwards would f Y the s ee of the bolt and the latter onli,7 hold the hasp against its but would prevent the Withdrawal oi" the haop and thus keep the door locked.

lWhat l claim as new is: i

l. ln a door fastener, ali-ning horizontal 'platee secured to a door, the one near it the forward edge oi 'the door having; its end opposite said edge A terminato in a staple the ree extremity ot' Which latter if; provided with a cross-head, and the plate itarthest 'from the 'forward edge ot the door having; a aoclet therein the entrance to which is ythe obverse et said head and elongated longitudinally, and a hasp connected to said staple, in combination Wit-h a counterpart member against the outer surface el Which said hasp is seated and having a socket on one side ot the seat ot the hasp and a loop ivo uid not Lannion.

opposite eaid edge terminate in a staple the' tree extremity of which latter is provided with a. cross-head, and the plate farthest 'from the 'forward edge olf the door having a pocket therein the entrance to Which is the obverse ot said head and elongated longitudinally, and a hasp connected to said shipleg in combination with a counterpart member against the outer surface of which said hasp is seated and having a socket on one eide ot the seat oit the hasp and a loop on the other side thereof, and a bolt for retaining; the hasp on its seat Whose ends enter end opposite said staple provided with a head which primarily engages the edge ot its een. farthest from said door. ,t

ln con'xliiination With the door and door trame ot a railwayT car, a fastening tor the door comprising a hasp on one ot said elements end :i locking: member on the other having" guides, a locking; pin in said guides io retain the haspi the lat-ter termed with a trmiererselv disposed head projecting in opl site directions Afrom the body ot the hasp. the inner portion of which head overlap and enero-es said locking member and the outiva lv projecting portion oit which stands adjacent to and in line With said pin., tor the purpose described.
